I just saw the notification of the kerneloops applet show up and disappear again and the syslog only says "kerneloops: Submitted 1 kernel oopses to www.kerneloops.org". I don't know what actually caused this oops or where to look the submit up on kerneloops.org. The applet should log the details of the oops and the url on kerneloops.org if possible so one can identify what actually happened.
